测量方法、 测量性能要求确定及服务小区选择方法及终端 技术领域
本发明涉及第三代移动通信***（3G, The 3rd Generation ) 中的终端异 频 /异***测量处理技术， 尤其涉及一种异频 /异***测量方法及其测量性能要 求确定方法、 及服务小区选择方法及其用户终端。 背景技术
通用移动通信*** ( UMTS， Universal Mobile Telecommunications System ) 是采用 WCDMA 空中接口技术的第三代移动通信***， 主要是在 WCDMA/GSM全球标准化组织 3GPP中发展。
其中在 3GPP UMTS标准中， 根据无线资源控制 （RRC, Radio Resource Control )连接是否建立， 可以将用户终端分为空闲 （Idle )模式和 R C连接 ( Connected )模式两种： 其中未与 UMTS通用陆地无线接入网 （UTRAN, Universal Terrestrial Radio Access Network )建立 RRC连接的用户终端处于 Idle 模式， 该模式下的用户终端只能通过非接入层（NAS， Non-Access Stratum ) 标识来区分， 如通过国际移动台识别号（IMSI, International Mobile subscriber identity )来区分； 其中已与 UTRAN建立 RRC 连接的用户终端处于 RRC Connected模式， 该模式下的用户终端被分配了无线网络临时标识（RNTI, Radio network temporary identity )， 以作为该用户终端在公共传输信道上的标 识。
而对于 RRC Connected模式的用户终端， 又可根据 RRC连接的层次和用 户终端能使用的传输信道类型将用户终端划分为不同状态： 其中 CELLJPCH 状态、 CELL—FACH状态和 CELL— DCH状态下的用户终端在小区层次上可以 区分, URA— PCH状态下的用户终端在 UTRAN登记区（ URA, UTRAN Register Area )层次上可以区分。 其中 CELL— DCH状态下的用户终端被分配了专用的 物理信道， 用户终端可使用专用传输信道和共享信道以及它们的组合； CELL— FACH状态下的用户终端在下行要连续监控一个公共传输信道 ( FACH, Forward Access Channel ), 在上行被分配缺省的公共信道 ( RACH, Reverse Access Channel ); CELL— PCH和 URA— PCH状态下的用户终端采用不连续接 收（DRX, Discontinuous Reception )方式通过相关的寻呼指示信道（PICH, Page Indicator Channel )监控一个寻呼信道（ PCH， Page Channel ), 这两种状 态下的用户终端没有任何上行活动。
在 3GPP UMTS标准中， 当用户终端处于不同模式和状态时，要根据接收 的***信息和自身所处小区的接收质量对异频小区或异***进行测量， 以进 行小区重选、 切换等处理。 其中处于 idle, CELL— PCH, URA— PCH 和 CELL— FACH状态下的用户终端对异频 /异***测量的触发条件是接收的*** 信息和当前所在小区的接收质量； 而处于 CELL JDCH状态下的用户终端对异 频 /异***测量的触发条件是***下发的***测量控制信息。 一般情况下， 对 于不具有双接收机的用户终端， 由于无法同时支持对两个不同频率上的信号 进行接收解码， 因此用户终端在进行异频 /异***测量期间会中断对当前小区 内信号的接收。
为了有效利用移动通信网络资源， 第三代移动通信***引入了组播和广 播的概念， 组播和广播业务是一种从一个数据源向多个目标传送相同数据的 技术。 由此， WCDMA/GSM全球标准化组织 3GPP提出了多媒体广播 /组播业 务（ MBMS, Multimedia Broadcast/Multicast Service ), 所谓 MBMS就是在移 动通信网络中提供一个数据源向多个用户发送相同数据的点到多点业务， 以 实现网络资源共享， 提高网络资源的利用率， 尤其是空口接口资源的利用率。
MBMS业务在用户终端 （UE, User Equipment )和 UTRAN之间的数据 传输模式可分为两种： 点到点（PTP, Point to Point )模式和点到多点（PTM, Point to Multipoint )模式。 其中 PTP模式用于 MBMS的组播模式， 组播模式 下的 RRC连接模式下的用户终端通过专用控制信道( DCCH, Dedicated Control Channel )接收控制信息、 及通过专用业务信道（ DTCH, Dedicated Traffic Channel )接收数据信息。 而 PTM模式用于 MBMS的广播或组播模式， 该模 式下的用户终端通过 MBMS 点到多点业务信道 （ MTCH , MBMS point-to-multipoint Traffic Channel )接收数据信息、及通过 MBMS点到多点控 制信道（ MCCH, MBMS point-to-multipoint Control Channel )接收控制信息。
用户终端监督的各个小区可以划分为以下三类：
1 )激活集小区： 用户终端信息在这些小区内发送； 用户终端只对包含在 小区信息列表中的激活集小区进行测量；
2 )监督集小区： 不包含在激活集小区内但包含在小区信息列表中的小区 属于监督集小区；
3 )检测集小区： 既不包含在小区信息列表中、也不包含在激活集小区中、 但用户终端可以检测到的小区属于检测集小区。 终端两种。
在 CELLJFACH状态下， 3.84Mcps TDD终端能够监督最多：
- 32个同频小区 （包括用户终端所在的当前服务小区）；
- 32个异频小区；这 32个异频小区中包含： TDD异频最多为 2个的 TDD 小区， 依靠用户终端能力 FDD载频最多为 3个的 FDD小区；
-依靠用户终端能力， 分配到 32个 GSM频率的 32个 GSM小区。
在 CELL— FACH状态下， 1.28Mcps TDD终端能够监督最多：
- 32个同频小区 （包括用户终端所在的当前服务小区）；
- 32个异频小区；这 32个异频小区中包含： TDD异频最多为 3个的 TDD 小区， 依靠用户终端能力 FDD载频最多为 3个的 FDD小区；
-依靠用户终端能力， 分配到 32个 GSM频率的 32个 GSM小区。
其中处于 CELL_FACH状态下的用户终端要进行异频 /异***测量处理， 以用于小区重选、 识别新小区等操作。 其中处于 CELL— FACH状态下的用户 终端会定位满足下列公式的***帧号 （SFN, system frame number ), 并在满 足该公式的***帧号中执行异频 /异***测量：
SFN div N=C RNTI mod M REP + n M REP (公式 1 ) 其中式中：
N是终端监控的承载非 MBMS 逻辑信道的辅助公共控制物理信道 ( SCCPCH, Secondary Common Control Physical Channel )上有最大发射时 间间隔（ TTI, Transmission Timing Interval ) 的 FACH的 TTI除以 10ms, 此 段时间是用户终端进行异频 /异***测量的时间持续长度；
M— REP代表测量间隔循环周期， M—REP = 2k; 由上式， 一个 N帧的测量 时间的重复周期是 NxM— REP帧； 其中 k是 FACH测量间隔循环周期系数， 可在***信息 11或 12所含的信息元素" FACH measurement occasion info"中读 取；
C
n = 0,l,2...， 只要 SFN低于其最大值。
用户终端在满足上述公式 1的异频 /异***测量时间中会连续对已识别的 异频小区 /异***小区进行测量， 并同时搜索在 UTRAN下发的***测量控制 信息中所指示的新的异频小区 /异***小区。
在现有标准中， 其中接收 MBMS PTM业务的频分双工（ FDD )终端对新 的异频小区进行识别的过程如下：
(一）用户终端接收 UTRAN下发的***测量控制信息， 读取***测量控 制信息中所指示的异频小区信息， 发现存在有未识别的异频小区；
(二）用户终端检测到未识别的异频小区 （用户终端通过在***测量控制 信息所指示的新的异频小区中的频率上工作， 如果发现在这个频率上接收信 号足够强， 就认为检测到了这个异频小区）；
(三）用户终端在下列公式计算得到的识别时间 T identify* inter内识别出上述检 测到的异频小区：
T

X dentify, inter A meas 1 v Freq.FDD
Figure imgf000006_0001
(公式 2 ) 上式中 Tbasic— identify—FDD，inter = 300ms或 800ms, 是用户终端识别新异频小区的最大 允许时间；
NFreq,FDD是***测量控制信息中的异频小区信息列表里包含的 FDD频率 数；
T = [{NFDD + NTDD + NGSM )- NTT1 . M_REP · 10] (公式 3 ) 其中在公式 3中：
ΝτΏ等于公式 1中的 Ν, M_REP参照公式 1中的解释；
NFDD等于 0或 1 , 如果在邻小区信息列表中有 FDD异频小区， 则 NFDD = 1， 否则 NFDD = 0;
NTDD等于 0或 1 , 如果在邻小区信息列表中有 TDD异频小区， 则 NTOD
= 1 , 否则 NTDD = 0;
NGSM等于 0或 1 , 如果在邻小区信息列表中有 GSM异频小区， 则 NQSM = 1 , 否则 NGSM = 0;
TInter FACH=(NTTIxlO-2x0.5)ms， ！^^等于公式 1中的 N。
(四）用户终端在自身存储的小区信息列表中将上述新识别出的异频小区 标识为已识别异频小区。
其中， 接收 MBMS PTM业务的 FDD终端对异频小区进行公共导频信道 ( CPICH, Common Pilot Channel )测量的过程如下：
(一）用户终端接收 UTRAN下发的***测量控制信息或***广播信息， 触发对异频小区的 CPICH测量；
(二） 用户终端的物理层在下列公式计算得到的测量周期 TMeasurement, Inter 内将测量结果上艮给高层： Freq'FDD
Figure imgf000007_0001
(公式 4 ) 式中: Tbasic—measurement— FDDsinter - 50mS;
Tjvieasurement— Period, Inter - 480lIlS;
其他参数参照上述公式 2和公式 3中的相应解释。
(三）用户终端的高层将物理层上报的测量结果用于内部算法（如该测 量结果可作为小区重选算法的输入参数）或上报给无线网络控制器（R C, Radio Network Controller )。
但是在实际应用过程中， 接收 MBMS PTM业务的 FDD终端在识别新的 异频小区、 对异频小区进行 CPICH测量时， 用户终端为保证 MBMS的解调 性能要求， 可能将不能使用按照公式 1 计算得到的整个异频测量时间进行异 频测量， 只能使用其中的部分异频测量时间进行异频测量。 然而用于求取用 户终端识别出新的异频小区的识别时间 Tidentify, inter的公式 2, 和用于求取用户 终端物理层将测量结果上报给高层的测量周期 TMeasurement, Inter的公式 4中的参 数 TtoerFACH NxnX lO xO^mS表示的含义是用户终端要使用按照公式 1计算 得到的整个异频测量时间进行异频测量处理。 这样就会导致下列问题出现： 如果用户终端在公式 2计算得到的识别时间 Tidentify，inter内识别出新的异频 小区， 在公式 4计算得到的测量周期 TMeasurement, Inter内将对异频小区的 CPICH 测量结果上^ =艮给高层， 则用户终端就要使用按照公式 1 计算得到的整个异频 测量时间进行异频测量,从而导致用户终端对接收的 MBMS的解调性能降低； 如果用户终端为保证对接收的 MBMS的解调性能， 使用按照公式 1计算 得到的部分异频测量时间进行异频测量， 则用户终端可能不能在按照公式 2 计算得到的识别时间 Tidentify, inter内识别出新的异频小区， 也不能在按照公式 4 计算得到的测量周期 TMeasurement, mter内将对异频小区的 CPICH测量结果上报给 高层。
上述过程在接收 MBMS PTM业务且处于 CELL— FACH状态下的 FDD终 端对异*** WCDMA TDD小区进行识别、 及对异*** WCDMA TDD小区主 要公共控制物理信道（PCCPCH, Primary Common Control Physical Channel ) 接收信号码功率（RSCP, Received Signal Code Power ) 测量结果的上报处理 也存在同样的技术缺陷。
在现有标准中， 接收 MBMS PTM业务的 FDD终端对检测到的属于监督 集内的新的异*** WCDMATDD小区进行识别时，要求在下列公式计算得到 的识别时间 Tidentify, TDD内识别出异*** WCDMA TDD小区：
Figure imgf000009_0001
(公式 5 ) 其中 Tbasic_identify— TDD,inter = 300ms或 800ms;
NFreq,TDD是***测量控制信息中的异频小区信息列表里包含的 TDD频率 数；
其他参数请参照上述对公式（2 )和公式（3 ) 的解释。
并要求用户终端的物理层在下列公式计算得到的测量周期 TMeasurement, TDD 内将对异*** WCDMATDD小区的 PCCPCH RSCP测量结果上报给高层：
ί 「了 Ί

(公式 6 ) 其中：
Tbasic— measurement— TDD, inter— 50 HIS, T easurement_Period_TDD,inter = 480 mS;
其他参数参照上述公式 2和公式 3中的相应解释。
这样也就相应存在如下问题：
如果用户终端在公式 5计算得到的识别时间 Tidentify，TDD内识别出新的异系 统 WCDMA TDD小区， 在公式 6计算得到的测量周期 TMeasurement, TDD内将对 异*** WCDMA TDD小区的 PCCPCH RSCP测量结果上^ =艮给高层，则用户终 端就要使用按照公式 1 计算得到的整个异***测量时间进行异***测量， 从 而导致用户终端对接收的 MBMS的解调性能降低；
如果用户终端为保证对接收的 MBMS的解调性能， 使用按照公式 1计算 得到的部分异***测量时间进行异***测量， 则用户终端可能不能在按照公 式 5计算得到的识别时间 Tidentify,TDD内识别出新的异*** WCDMA TDD小区， 也不能在按照公式 6 计算得到的测量周期 TMeasurement, TDD 内将对异*** WCDMATDD小区的 PCCPCH RSCP测量结果上报给高层。
其中， TDD终端要每隔时间 Tmeas, 周期性的测量 FDD异频小区、 TDD 异频小区和 GSM小区， 其中 Tmeas满足如下公式要求：
Tmeas = [{NFDD + NTDD + NGSM ) · NTTI · M_REP .10] (公式 7 ) 式中各参数的意义具体请参照上述公式 3中的解释。
TDD终端会在这些异频 /异***测量时间内连续测量已识别的异频小区， 并搜索在 UTRAN 下发的***测量控制信息中所指示的新的异频 /异***小 区。
在现有标准中，接收 MBMS PTM业务的 TDD终端对异频 /异***小区执 行测量的过程如下：
(一 ) TDD终端接收 UTRAN下发的***测量控制信息， 根据***测量 控制信息触发对相应的异频 /异***小区执行异频 /异***测量处理；
(二）TDD终端在上述公式 1计算得到的测量时间内和 /或空闲时间（ TDD 模式在一帧内分上下行时隙， 对于 TDD终端既不接收也不发射的时隙就为此 TDD终端的空闲时间） 内执行异频 /异***小区测量处理； TDD终端在异频 / 异***小区测量时间内要中断对 MBMS PTM业务的接收；
(三） TDD 终端在不执行异频 /异***测量的其余时间进行接收 MBMS PTM业务。
但是在实际应用过程中， 由于接收 MBMS PTM业务的 TDD终端在进行 异频 /异***测量处理时， 会中断对 MBMS PTM业务的接收， 由于在大部分 情况下， 每个 TDD终端对 MBMS PTM业务接收中断的时间点不同， 因此网 络侧很难确定该重发哪些没有被 TDD终端接收到的 MBMS PTM业务信息， 因此就会造成 TDD终端对 MBMS PTM业务的接收质量差。 在现有标准中， 其中接收 MBMS PTM业务的 TDD终端对新的异频小区 进行识别的过程如下：
(一 ) TDD终端接收 UTRAN下发的***测量控制信息， 读取***测量控 制信息中所指示的异频小区信息， 发现存在有未识别的异频小区；
(二） TDD终端检测到未识别的异频小区 （用户终端通过在***测量控制 信息所指示的新的异频小区中的频率上工作， 如果发现在这个频率上接收信 号足够强， 就认为检测到了这个异频小区）；
(三） TDD终端在下列公式计算得到的识别时间 Tidentify, inter内识别出上述 检测到的异频小区：
其中 3.84Mcps TDD终端识别监督集小区内的一个新检测到的异频 TDD小 区所需的时间性能要求为：

其他参数参照上述公式 2和公式 3中的相应解释。

此外， 接收 MBMS PTM业务的 TDD终端对异频 TDD小区进行主要公 共控制物理信道 ( PCCPCH, Primary Common Control Physical Channel )测量 的过程如下：

但是在实际应用过程中， 接收 MBMS PTM业务的 TDD终端在识别新的 异频 TDD小区、 对异频 TDD小区进行 PCCPCH测量时， TDD终端为保证 MBMS的解调性能要求， 可能将不能使用空闲时间和 /或按照公式 1计算得到 的整个异频测量时间进行异频测量， 只能使用其中的部分异频测量时间进行 异频测量。然而用于求取 TDD终端识别出新的异频小区的识别时间 Tidentify,inter 的公式 8和公式 9，和用于求取 TDD终端物理层将 PCCPCH测量结果上报给 高层的测量周期 TMeasurement , Inter的公式 10 和公式 11 中的参数 TInter

如果 TDD终端为保证对接收的 MBMS的解调性能， 使用部分空闲时间和 / 或按照公式 1计算得到的部分异频测量时间进行异频测量， 则 TDD终端可能不 能在按照公式 8和公式 9计算得到的识别时间 Tidentify, into内识别出新的异频 TDD 小区，也不能在按照公式 10和公式 11计算得到的测量周期 TMeasurement, Inter内将对 异频小区的 PCCPCH测量结果上^ =艮给高层。
上述过程在接收 MBMS PTM业务状态下的 TDD终端对异*** WCDMA FDD小区进行识别、 及对异*** WCDMA FDD的公共导频信道（ CPICH, Common Pilot Channel ) 测量结果的上报处理也存在同样的技术缺陷。

按照本发明提出的异频 /异***测量方法， 接收 MBMS PTM业务的 TDD 终端执行异频 /异***测量处理的具体实施过程可以如下：
